Ask for special fares from Nanning to Beijing.

Generally, it is almost half a month in advance, and it is not necessarily cheap if it is too early. The fare is changing at any time. If it is confirmed, it must be sold immediately. Don't choose the peak season, such as the Spring Festival. Now many websites have good services, such as E Long Travel Network, where my friends and I have been buying and the after-sales service is good. However, there are three restrictions on special airfare, that is, cheap airfare, so you must take it if you buy it, or you will lose a lot. It is also good to buy tickets on the airline website.
